How many days are there in a year?

Answer 1

There are about 365.2422 days in a year.

That's why every fourth year is a leap year unless it is divisible by 100, but it still is a leap year if divisible by 400.

(So the year 2000 was the only even century leap year so far, the year 1600 was before this standard was adopted).

There are many different definitions of a year so there are different lengths. some are listed below:

• 346.62 days: a draconitic year.
• 353, 354 or 355 days: the lengths of common years in some lunisolar calendars.
• 354.37 days (12 lunar months): the average length of a year in lunar calendars, notably the Muslim calendar.
• 365 days: a vague year and a common year in many solar calendars.
• 365.24219 days: a mean tropical year (rounded to five decimal places) for the epoch 2000.
• 365.2424 days: a vernal equinox year (rounded to four decimal places) for the epoch 2000.
• 365.2425 days: the average length of a year in the Gregorian calendar.
• 365.25 days: the average length of a year in the Julian calendar.
• 365.2564 days: a sidereal year.
• 366 days: a leap year in many solar calendars.
• 383, 384 or 385 days: the lengths of leap years in some lunisolar calendars.
• 383.9 days (13 lunar months): a leap year in some lunisolar calendars.

365 1/4

Note:having a leap year would only add one more day to the year.So in a Leap year it would be 236.
Stricly speaking there a re 365 and a quarter, but we only have 365, then add up the quarters ever four years and have an extra day, making 366 days. Those are leap years and I think the next one is in 2008.
